The study area is situated in the Lake District of southwest Turkey. The Eğirdir and Burdur lakes are the most important ones in this region due to their size and water potential. The extensive Atabey and Keçiborlu plains that are located between these lakes receive irrigation water both from Eğirdir Lake and from groundwaters. Throughout this region, the demand for irrigation water has increased steadily over recent years. The aim of this work was to investigate the water quality and potential across this region, using hydrogeological, hydrological and hydrogeochemical techniques. The hydrochemical and isotopic characteristics of both the lakes and the groundwater of the study area were determined. Eğirdir lake and the groundwaters of the Atabey and Keçiborlu plains are Ca+2-Mg+2-HCO3- type waters, whereas Burdur lake contains Na+-SO4-2- (Cl-)- HCO3- type waters. The 518O, 52H and 3H isotopic contents indicate that both the lake waters and the groundwater in the aquifers between these lakes are young and of meteoric origin. Groundwater is the most important sources for supplying future enhanced demands for irrigation water in this region, from the point of view of water quality and availability.
